A readable introduction to particle physics?

[scissy]

Does anyone know of one (for adults preferably!) Saw professor Higgs at the Cheltenham Science festival yesterday and realised my physics a level really didn't cut it

This? Bit pricey but there may be a cheaper paperback one on ebay.

Try 'How To Teach Quantum Physics To Your Dog'. It's humerous but also introduces the concepts in a very approachable manner.
